Description
Technical field
The invention belongs to composite pipe technical field, relate to the making of glass fiber reinforced plastic sand-inclusion pipeline, specifically a kind of heavy caliber
The processing method of buried RPM
Background technology
The heavy caliber draining of current domestic use, blow-off line use traditional pipe of concrete and fiberglass sand inclusion substantially
Pipe, traditional pipe of concrete because doing concrete floor when engineering comb, and has considerably long curing period quickly not execute
Work, and pipe of concrete Heavy Weight, the most seriously add the difficulty of construction.Consider disadvantage mentioned above, therefore when urban road is reconstructed
Mostly it is designed with high-strength light, is not required to do basic RPM.
Glass fiber reinforced plastic sand-inclusion pipeline is a kind of using unsaturated polyester resin as matrix material, glass fibre and goods conduct thereof
The novel glass reinforced plastics composite pipeline that reinforcing material and quartz sand are made as packing material, is divided into pure glass according to pipe structure difference
Glass steel conduit and glass fiber reinforced plastic sand-inclusion pipeline two kinds, pure GRP pipe bear intrinsic pressure preferably, stable performance, but it is low to carry outward rigidity.
Glass fiber reinforced plastic sand-inclusion pipeline is to add the fillers such as quartz sand in process of production, in order to improve external rigidity, with pure GRP pipe
Compare and there is rigidity greatly, the advantage of low cost, but also have weight big, flimsy deficiency.
Conventional glass fiber reinforced plastic sand-inclusion pipeline structure is divided into three layers: inner liner, structure sheaf and external protection.Current this pipeline
Generally using wet method to prepare, this preparation method is first to be soaked with unsaturated polyester resin on the surface wrap of pipe mould
Glass fiber bundle also solidifies and makes inner liner, and then surface is covered with the damp sand being made up of quartz sand and unsaturated polyester resin
The glass fiber yarn Fabric tape winding of bar makes structure sheaf on the surface of inner liner solidification, finally uses on the surface of structure sheaf
External chiasma hoop mode is wound around and is soaked with the glass fiber bundle of unsaturated polyester resin solidification and makes external protection.This often
Glass fiber reinforced plastic sand-inclusion pipeline there is corrosion-resistant, aging resistance and high-strength light, antiseepage, nontoxic and smooth surface, conveying liquid
Features such as resistance is little, can guarantee that water supply quality, anti-chemistry and galvano-cautery, and construction costs can be reduced, have simultaneously easy for installation,
Service life length, the feature such as comprehensive cost is moderate, simple to operate, maintenance cost is low, be the most gradually popularization and application
A kind of flexible composite pipeline.But still come with some shortcomings, the wearability such as inner liner is slightly worse, and liner is through the most substantial amounts of
Current scour, there is substantially layering in tube wall, fiber tensile failure, come off, the phenomenon such as fracture, bring huge hidden to safety
Suffer from, and cost is higher, again environmental protection not.
Summary of the invention
The technical problem to be solved is the deficiency existed for prior art, it is provided that a kind of buried glass of heavy caliber
The processing method of glass steel clamp sandpipe.
In order to achieve the above object, the present invention is by the following technical solutions.
The processing method of the buried RPM of a kind of heavy caliber, comprises the following steps:
(1) modified steel fiber, modified carbon fiber and modified glass-fiber are pressed the weight ratio shuffling of 5-15:15-20:65-80
Become fiber felt, immerse in unsaturated polyester resin, form the fibre felt layer A containing unsaturated polyester resin 80-90wt%；Described
Steel fiber surface is coated processing and obtains by modified steel fiber, and the modification liquid of coating processing is silicone oil, silane coupled
The weight ratio that 1:0.01:100 is pressed in agent, water is formulated；Described modified carbon fiber is to carry out carbon fiber at electrochemical oxidation
Reason obtains；Described modified glass-fiber aluminate coupling agent processes and obtains；
(2) modified glass-fiber is become fiber felt with modified carbon fiber by the weight ratio shuffling of 85-95:5-15, immerse insatiable hunger
With in polyester resin, form the fibre felt layer B containing unsaturated polyester resin 40-50wt%；
(3) step fibre felt layer A (1) uses definite-length-winding process hoop be wrapped in the surface of pipe mould solidification and
Making inner liner, then the step same hoop of fibre felt layer B (2) is wrapped on inner liner, forms inner protective layer；
(4) 100-200 mesh quartz sand, short glass fiber, magnesium borate crystal whisker, unsaturated polyester resin are pressed 85:4:1:10
Weight ratio mixing, obtain batch mixing sand bar, its hoop be wrapped on step inner protective layer (3), formed burning into sand layer；
(5) step fibre felt layer B hoop (2) is wrapped on step burning into sand layer (4), forms external protection, by unsaturation
Polyester resin, short glass fiber, magnesium borate crystal whisker press the weight ratio mixing of 85:13:2, the reciprocating hoop of compound obtained
Be wrapped on external protection, form extexine, till reaching the wall thickness of design, carry out after cured repairing, the demoulding, cleaning inspection
I.e. can get finished product.
The Advantageous Effects of the present invention: the multiple structure RPM that the present invention makes overcomes in prior art
Clamp sand pipe inner liner wearability is slightly worse, and life-time service tube wall there will be substantially layering, fiber tensile failure, come off, fracture etc. existing
As problem.The clamp sand pipe bore made is big, has corrosion-resistant, aging resistance and high-strength light, antiseepage, nontoxic and smooth surface, defeated
Send that liquid resistance is little, can guarantee that water supply quality, the feature such as anti-chemistry and galvano-cautery, and construction costs can be reduced, there is peace simultaneously
The features such as dress convenience, length in service life, comprehensive cost is moderate, simple to operate, maintenance cost is low.
